KUROMIfy the World Project

The KUROMIfy the World Project (世界クロミ化計画 ) is an ongoing project featuring Kuromi, with a theme of being the best you can be. Revealed on October 26, 2021, the KUROMIfy the World Project started on Halloween 2021 with the release of Kuromi's digital single Greedy Greedy. A teaser video was made available on the official site ahead of release. Fans of Kuromi following the project are called KUROMIES.

Development
Kuromi's generation Z fans are noted as worrying about "selfishness" and who they want to be, this was observed to be even more the case after the Covid-19 pandemic, which gave people more time for introspection. Due to this, the project was launched with Kuromi, striving to become her best self and to help create a world where everyone can do the same.

Promotion
A hashtag: #KUROMIfytheWorld (as well as a Japanese version: #世界クロミ化計画 ) was started.

Beginning from October 26, 2021, promotional posters were put up in Shibuya City featuring the project's logo, the Japanese hashtag and the release date of Greedy Greedy. Some variations of the poster included Kuromi's signature and skull logo.

Following the release of Greedy Greedy, the website was updated to feature profile icons to be used by KUROMIES, all featuring a modified version of the project's logo, available in various colours.

Songs
On October 31, 2021, the first song Greedy Greedy was released.
